Procedure for sealing watertight containers of liquids, in which a portion of extruded tube in thermoplastic material, hot introduced inside a mold, is deformed by a fluid injected under pressure inside, until the outside of the tube is adapted against the internal walls of the mold, obtaining a hollow, closed body, provided with a conduit for access to its interior, through which liquid is introduced until its total filling, characterizing the procedure by the fact that the body it is immobilized by means of a support base and an upper piece that fits against its surface, the part provided with a through opening in which an external tubular extension of the body, which constitutes the access conduit to its interior, is strung, the opening acting as a guide to a welding arrangement which, at a suitable temperature, is applied under pressure against the conduit, determining its fusion and the closing of the access to the interior of the body, lodging the excess material in this interior.
